For the best way to improve you and your team's motions, just do this.......LOOK IN A MIRROR.

It sounds easy and it works.  By watching yourself OR having your team watch themselves.  You/they will see where they are hitting their motions and how they can improve them. 

So practice your motions at home OR you can try to get your team in a studio where there's a huge mirror.  It will make great changes in such little time.
